Frequently Asked Questions
These estimates are based on average Unity asset sizes and provide a rough approximation. Actual build sizes can vary significantly based on compression settings, asset complexity, and Unity optimization features. Use this tool as a starting point for planning, but always test with actual builds.
Different platforms have varying compression algorithms, supported texture formats, and optimization capabilities. WebGL typically has better compression, iOS uses specific texture formats, and Android builds may include multiple architecture support, affecting final size.
Typically, textures and audio files are the largest contributors to build size. High-resolution textures, uncompressed audio, and large 3D models can significantly increase your build size. Focus on optimizing these assets first.
Key strategies include: enabling texture compression, using Asset Bundles for dynamic loading, enabling code stripping, optimizing audio compression, reducing unused assets, and using Unity's built-in optimization tools like the Build Report window.
Yes! Google Play has a 150MB limit for APK files, and Apple App Store recommends keeping apps under 200MB for cellular downloads. Use App Bundles (Android) or implement content streaming to work around these limits.
